Cisco MGX 8850 Series

Multiservice Switch

The Cisco MGX® 8850 Advanced ATM Multiservice Switch enables delivery of a complete portfolio of differentiated service offerings while scaling from DS0 to OC-48c/STM-16 speeds.

Based on the industry's most extensible architecture, the Cisco MGX 8850 provides the greatest flexibility at the service provider edge. Multiple, simultaneous control planes support unmatched flexibility and scalability in deploying, managing, and modifying a complete range of ATM, Multiprotocol Label Switching (MPLS), and voice services.

Scalable Configurations

Using the Cisco PXM-1 Processor Switching Module Card option for edge concentration, service providers can deploy a complete set of narrowband services with 1.2 Gbps of nonblocking switching for low-density or remote deployments.

Using the Cisco PXM-45 Switching Card option, service providers can implement a complete range of narrowband services for high-density edge applications and broadband aggregation with 45 Gbps of nonblocking switching. The Cisco PXM-45 can also be used exclusively for broadband aggregation and backbone functions.

The Cisco WAN Manager Service Agent can also be used to provide a northbound SNMP Application Program Interface (SNMP API) for seamless integrations with operations support systems (OSSs) and third-party network- and service-management systems. The Cisco WAN Manager Service Agent enables flow-through provisioning and fault-management capabilities that service providers demand.

Mechanical Configuration

•32 single-height (16 double-height) function module slots

–The single-height slots can be in-service slots converted to double-height slots by removal of midrail dividers

Optional Redundancy

All components are optionally redundant to 100-percent system redundancy, including the control processor, IP modules, switching fabric, network interfaces, service interfaces, critical backplane signals, power supplies, power modules, and cooling fans.

Node Synchronization

•Internal Layer 3 clock source

•External T1/E1 Building Integrated Timing Supply (BITS) source

•External source received in band over the network

•Synchronization to software-programmable primary and secondary sources, with automatic switchover
